I am in AP Calculus BC and skipped algebra 2 so i hope that i can help you.


From about 5 minutes of work i can tell you

2 is b
9 is -7/10
10 is -2
11 is c
13 is d
15 is b


A lot of the questions are unanswerable because of missing images.

If you need more help just pm i will guide you through it.

Oh and try www.physicsforum.org i find that it can help a whole lot and their "mods" literally do nothing but help people solve problems.
